The small fan pushes down the warm air at the top of the box down along the cooling wall at the back, forcing the temperature sensor at the left to give a cooling signal to the compressor.
In our fridge I have mounted a small 12 Volt fan. It's controlled by the compressor of the fridge: if the refrigerator switches on, the fan starts blowing.
This air circulation in the coolbox enhances the spreading of the temperature. With the fan off, and the board computer on 5 Celsius, on warm days I sometimes measure 4 degrees at the bottom of the fridge and even 10 to 12 Celsius just under the lid. The difference is amazing.
With the fan on I measure between 7 to 8 degrees Celsius, depending very much on the outside temperature of course.
Under the fridge in our T5 I've mounted a second fan.
The fan is pulling hot air from the compressor department.
With a switch I can cut off the current to the fan, just in case its sound keeps us out of sleep. Which isn't the case, I can hardly hear the fan working, even with the closet door open.
Does it help? Yes it does. On warm days the fan sucks enough warmth from under the compressor to keep the fridge going. The compressor also does start less frequently to cool the box. Although I must add, that since our solar panels we hardly use the battery loader, so there's less heat under the fridge.
